Am trying to create live mpeg-dash Clear streams by taking UDP stream as the input. Below are the steps used for conversion and package it

Step 1 : Publish point creation and server manifest file creation

mp4split --license-key=/mnt/usp-license.key --database_path=www/live/channel1/channel1.db3 -o /www/live/channel1/channel1.isml --archiving=1 --archive_length=600 --archive_segment_length=10 --dvr_window_length=300 --restart_on_encoder_reconnect

Step 2 : ffmpeg for ismv file creation

FFMPEG_OPTIONS="-movflags isml+frag_keyframe -f ismv -threads 0"
AUDIO_OPTIONS="-c:a aac -strict experimental -ac 2"
VIDEO_OPTIONS="-c:v libx264 -preset fast -profile:v main -r 59.97 -g 60 -keyint_min 60 -sc_threshold 0 -pix_fmt yuv420p"
MAP="-map 0:v -b:v:1 1072k -minrate 1072k -maxrate 1072k -bufsize 2144k -s:v:1 960x540
-map 0:a:0 -b:a 128k"

CMD="-y -re
-i $1

ffmpeg $CMD

Step 3: Request to manifest filehttp://IP-Address/channel.isml/manifest.mpd...

Playback Error :

1) From Android device Exo-player,the stream is playing but it is not smooth and having pixel issue,after every 10sec playback the video is freeze for a second and playback continues

2) In Microsoft Edge browser, when we try to play the same stream through Dash.js script it played for couple of minutes and got the Error in apache error log as 'FMP4_IO_NO_SUCH_FILE_OR_DIRECTORY' .

Can you help us in this issue , why playback is not smooth and why same stream got different error while trying from EDGE browser

You should not use an ip address but a hostname in both the fmpeg script and the apache virtual host, as outlined here:


Please follow this as well:


Did you first follow the 'verify your setup' so you have a working install?

Kind Regards,
